We systematically studied the chemical reactivities of 13 metal–organic frameworks (MOFs) under vapor-assisted aging (VAG) at room temperature. The MOFs aged in solvent vapor at room temperature showed unexpectedly high reactivities for transformations in

Two types of 2D [RMI]2[Zn3(BDC)3X2] (Type A) and 3D [Zn(BDC)(H2O)] (Type B) (H2BDC = 1,4-benzenedicarboxylate acid) compounds were synthesized with three kinds of 1-alkyl-3-methyl imidazolium halide ([RMI]X) ionic liquids. Type A is the primary structure model showing a (3,6) network. Type B can be obtained from [BMI]Cl, [AMI]Cl and [AMI]Br media, showing a 4,4-connected {42·84} network. The structure, TG, and fluorescence analyses demonstrate the combination effect of the RMI+ templating effect and X- controlling the structure types. The boundary between Types A and B is from [PMI]Cl, via [BMI]Br, to [AMI]I as the reaction media. The decomposition temperatures of the compounds in Type A decrease with increased RMI+, while X- anions exert the influence that compounds containing Br- supply the highest thermal stability. Similarly, with increased RMI+, or X = I-, the compounds show red shifts compared to the emissions of the ligand.

Interconversion made easy: Metalorganic frameworks (MOFs) are surprisingly reactive under grinding conditions and can perform various rearrangements (see picture). In this respect, the results reveal clear parallels between MOFs and organic molecular mate
Fabrication of nanosheets of a fluorescent metal-organic framework [Zn(BDC)(H2O)]n (BDC = 1,4-benzenedicarboxylate): Ultrasonic synthesis and sensing of ethylamine

A supramolecular metal-organic framework (MOF) constructed by two-dimensional (2D) infinite coordination polymers, [Zn(BDC)(H2O)]n (1, BDC = 1,4-benzenedicarboxylate), was synthesized by the reaction of zinc acetate with H2BDC in dimethylformamide (DMF) under ultrasonic irradiation at ambient temperature and atmospheric pressure. Yield of 1 varied from 43.4% to 53.2% for the reaction time of 10-90 min. Samples with different morphologies, i.e. nanobelts, nanosheets, and microcrystals, were obtained under ultrasound irradiation for different reaction times. Fluorescence emission of nanosheets of [Zn(BDC)(H2O)]n was found to be highly sensitive to ethylamine, and solid state fluorescence intensity decreased with increasing contents of ethylamine in acetonitrile solution due to weak fluorescence quenching effect.
Topological control in coordination polymers by non-covalent forces

Reaction of Zn2+ salts with the terephthalate dianion results in a herringbone motif coordination polymer; the orientation of the terephthalate spacer ligands and the coordination geometry about the Zn2+ ion is crucially dependent on hydrogen bonding to ancillary ligands; replacement of coordinated water with ethylenediamine results in marked changes to the polymer orientation without disruption of the fundamental features of the material.
